| 摘要 |
The present invention provides a fuel cell electrically conductive element with a polymeric surface comprising a flow field, at least a part of the flow field having a grafted, permanently hydrophilic, polymer coating. The element is made by applying a layer of a monomer mixture of a hydrophilic, ethylenically-unsaturated monomer and a crosslinking monomer to the electrically conductive element surface and polymerizing the applied monomer mixture layer with a plasma whereby the polymerized layer is grafted to the polymeric surface.
